COMBINATION TUBING DRAINER AND FULLER.

Application filed. August 8, `1925. Serial No. 48,969.

Toall whom t may concern:

Be it known that I, GEORGE VViLsoN Goss, a citizen of the United States,residing at Wichita Falls, in the county of Wichita and State of Texas,have invented certain new and useful Improvements in Combination Tubing`Drainers and Fullers, of which the vfollowing is a specification.

This invention relates to well pumping equipment and it has particularreference to a certain improvement in standing valve structures, theprimary object of which is to provide an eiiicient means whereby that felement may be automatically opened while within the well tubing by theactuation of the traveling valve thereabove, to permit thesaid tubing tobe drained of its contents preparatory to pulling, thus to obviatepossible loss accruing from waste of fluid resultant from such pulling.

The invention also contemplates in its provisions, a locking `mea-nswithin the standing valve, whereby to hold its valve in open position,should it bev required to also withdraw the standing valve, as a furtherexpedient in the saving of time.

Further, the invention aims in its objects to arrange said valve openingmeans in such a manner as to unseat the valveon the upward stroke of thetraveling valve, to thus overcome. the excessive weight of tliefluidbearing on the valve.

- Still further, certain other modifications are provided in theinvention, when required to use either the tubing drainer or the valvepuller alone. Y

Vith the foregoing and otherobjects and advantages in view, theinvention has particular reference to certain novel features ofconstruction-and assembly of parts,by which these objects are attained,which will be set forth and manifested in the course of the followingdetail description and illustrated in the accompanying drawings, whereinFigure 1 represents a view in vertical elevation, appearing partly insection.

Figure Q is also a view in vertical elevation of the standing valve inaxial crosssection, showing the draining mechanism therein.

Figure 3 represents a vertical elevational view ofthe inventionextended.

Figure 4 is a modified form of the inv/vention in vertical elevation,from which the valve pulling arrangement has been deleted, showing'thevalve in open position.

Figure 5 is a fragmentary sectional'view of the structure illustrated in`Figure 4, showing the valveV seated.

Figure 6 is a detail view of the rotating plug, which is adapted to bethreaded into the lower end of the traveling valve.

Figure 7 is a further modified formfof .i

the invention, in which the elements thereof are limited to a valvepulling device, and Figure 8 is a further view of Figure l7 in verticalelevation, showing collar in place thereon.

In proceeding in accordance withthe foregoing,` 1 denotes the standingvalve body, which is positioned at a point adjacent the bottom of thewell tubing, not shown. The valve body does not depart from the usualconstruction in such cases, but `is provided with a plurality' ofsuperimposed leather packing rings 2, circumferentially Ysurrounding thelower portion 8 of the body 1. I Within the cage 4, the usual kball`valve 5 is disposed upon the ,seat 6 provided by the lower portionStherefor. Thebodyof the valve is diminished at 6, directly above thecage 4, providing a shouldery 7, whereon is i seated a compressionspring 8.` Reciprocable freely within the diminished portion 6a, is a.plunger head 9, clearly illustrated in Figure 2, and to the bottom ofwhich is be receivedl by pins 16, situated upon the diminished portion6a of the valve.V Itis yunderstood that this collar 14 isV screwed Vuponthe lower end of the traveling valve and is actuated thereby.

The traveling valve, with which the.l pres ent invention operates, hasnot been illus,-

'trated in the drawings as its construction is well known, however, thelatter is arranged to be simultaneously drained with .the drainingof thestanding valve, which function is performed by the rod 173,l

the pulling vsecurely alhxed a spring leaf or tongue` 10, i

"L shaped slots 15.

threaded into the plunger head 9 and eX- tendrng upwardly into thetraveling valve, whereby to engage with and dislodge its valve upondownward stroke of the said.

traveling valve. This acti-on causes release Iof the liquid suspended bythe traveling valve, as well as that retained above the standing valve.

The valve locking means, as mentioned 1n the "foregoing, constitutes inaddition to 'the llinger 11, aslot 1S in one side ofoneof the aperturesforming the cage 1 and upon pressure of the head9, imposedbythe-downward action of the traveling valve, the finger 11 assumes a`position at a level with the slot 18, and rotation imparted to thetraveling lvalve Vthrough the sucker rod -upon which Athe same .ismounted, causes the Afinger 11 to Venter vthe slot 18, to thereby /holdthe head 9 from upward movement; The valve may be held in this positionduring the pulling ofthe tubing or may be reversely `rotated to releasethe valve., should 1t be desired to only Adrain vthe tubing land .valvestoY dispense with sand settlings and other extraneous matter accumulatedtherein.

It beingassumed in general practice, that the lstanding valve occupiesIa position adjacentthebottom-ofthe well, Iwhile the collar 14, shown inengagement with the dimmished portion y6n of the valve body 1, 1srigidly screwed upon the bottom .ofthe traveling valve (not shown).their v1t 1s required to drain the tubi-ng preparatory to pulling, thetraveling val-ve is lowered to effect Ian engagement as shown, wherebyto aline the slots 15 of the collar 14 with the pins 16 disposed -up'onthe portion 6a. Further downward `pressure causes compression of thespring 8, due to its Vengagement by the pins 12 ofthe head 9, upon whichythe collar 121 rests. lhen the head .9 reaches its lowest point, theltongue 10 `assumes a position between the ball-valve 5 and vthe wall ofthe cage 4:, preparatory to raising the `ball 5 upon upward movementofthe travelling valve.

It is well known that the weight -of the volume of oil contained withinthe :entire tubing is excessive, and -in several instances, attemptshave :been made to iin-seat the valve -by mechanism Vactuated rby thedownward action-of the traveling valve, but due to the `enormousweight-of the fluid, these attempts have thus far yproved unsuccessful.Therefore, the present invent-ion lprovides for a slight expansion ofthespring S, after engagement .of the collar 111 with the standing valve,to cause depression-of the head 9, such 'expansion being permitted by-an offset portion a in the lateral portion of the inverted Vhenengagement oi the latter with the pins 16 is accomplished to place thetongue 10 in the position as vpreviously set forth, the col-lar 14 isrotated `to permit the pins 16 lto vbe received vby itheolfset a, thusaffording a slight lexpansion of the spring S, sufficient to raise theball 5 a suitable distance upwardly -to allow passage of the fluidthereby. ln this manner, a greater lift may be Iaccomplished to overcomethe weight of the fluid against the ball.

The two modifications and their associated elements, illustrated inFigures et to 8 inclusive, may be employed when yrequired to alternatelypull or drain the tubing. The structure illustrated in Figure 4 Visprovided with the usual cage having a tubular lneck 17 thereon, throughwhich a plunger 18" reciprocates, which latter is provided with aslotted head 18u, as shown. This plunger is controlled in its movementAby a compression spring 19, disposed interiorly lof the neck. Thefunction of this structure is similar to that shown in Figure 1,however, the pulling arrangement constituting the collar 14 is obviated.Such arrangement is replaced by the slotted head '18, arranged torecei-ve the rotating plug 20, shown in detail in Figure 6, which Aismounted upon `the lower end of the traveling valve and is rotated fto inturn rotate the plunger 18 whereby to lock the. tongue 10 in the.position illustrated in Figure 4f.

ln Figure 7 is shown a vdevice iin which the tubing drainer arrangementiso'bviated.

This device Vconsists ofthe usua'lstanding valve provided with a neck21, having extending therethrough, a horizontal pin below which isretained a compression spring 23. The'collar 24;, similar to `thelcollar 1-1, shown lin Figures 1, 2 and 3, -is also mounted upon thelower end of the traveling valve, not shown, and the slots Q5 therein-arealined to receive the pins 22 on the neck 21, whereupon the suckerrod is rotated to lock the collar 9A- in the position shown in Figure 8,whereby to withdraw the valve.

The invention has been described as including all the elements set forthinthe 'appended claims, however it should be herein understood thatcertain minor changes and modifications may be made in the inventionwithout departing lfrom the spirit-and lintent thereof, or the subjectmatter-of saidclaims.
